Smallscale gold mining in southern Ecuador is causing considerable environmental impacts, the most important of which are related to the discharge of metals and cyanide into adjacent rivers. In the rivers, these contaminants are generally not present in watersoluble forms, but are associated with suspended particles and riverbed sediment.
